Cigarette inner wrapping papers currently used in the market mainly consist of four types: aluminum foil composite inner wrapping paper, aluminum vapor deposition transfer inner wrapping paper, vacuum aluminum vapor deposition inner wrapping paper, and aluminum-free inner wrapping paper. There are types. Due to differences in the moisture permeability index of the inner wrapper and its calibrated moisture content (5% ± 1%), once the cigarettes are packaged and placed on the market, the cigarettes will be subject to differences in storage time and environmental relative humidity and temperature.
